A box of mass 10 kg is pushed across the floor with a force of 25 N. A 2 N frictional force opposes the motion.

What is the acceleration of the box?

Fnet=Fp-Ff

ma=Fp-Ff

Let a= acceleration. Solve for a:

10kg*a=25N-2N

a=23N/10kg

a=2.3m/s^2

To find the acceleration of the box, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

1. First, let's find the net force acting on the box. The net force is equal to the applied force minus the frictional force.
Net force = Applied force - Frictional force
= 25 N - 2 N
= 23 N

2. Next, we can calculate the acceleration using Newton's second law:
Acceleration = Net force / Mass
= 23 N / 10 kg
= 2.3 m/s²

Therefore, the acceleration of the box is 2.3 m/s².
